By providing a plurality of first air outlet grooves 2172, when the heating component 22 is mounted in a mounting hole 216, the second air outlet groove 2173 is blocked. As a result, the heating component 22 cannot ventilate normally. It may be understood that in some other embodiments, a quantity of air outlet grooves 2172, 2173 is not limited to three. In some other embodiments, a quantity of air outlet grooves 2172, 2173 may be one or more than three, and a quantity of air inlet grooves 2171 may be one or more. When a plurality of air inlet grooves 2171 or a plurality of air outlet grooves 2172, 2173 are provided, ventilation efficiency of the heating component 22 may be improved, and a problem of liquid leakage may be resolved. That is, there is a bending area, which may make it difficult for the vaporization medium to leak downward.

As shown in FIG. 3 to FIG. 8 , in this embodiment, the heating component 22 may include a vaporization core 221 and a heating element 222; and the heating element 222 may be arranged on the vaporization core 221. The heating element 222 may be arranged on the vaporization core 221, and may be used to heat the vaporization medium on the vaporization core 221 to cause the vaporization medium to be vaporized and form vapor.

The vaporization portion 2212 may be integrally formed with the liquid guide portion 2211. The inner sleeve 212 may be sleeved on the vaporization portion 2212, and may be fixedly connected to the vaporization portion 2212 through an interference fit. The vaporization cavity 214 may be formed in the inner sleeve 212 and be located in upper space of the vaporization portion 2212. In this embodiment, the heating component 22 may include a vaporization surface 2214. The vaporization surface 2214 may be formed on the vaporization portion 2212 of the vaporization core 221, and may be arranged toward the air outlet channel 213.

In this embodiment, the heating element 222 may be arranged on the vaporization surface 2214. The heating element 222 may be a heating film, and the heating film may be fixed on the vaporization surface 2214 by sintering. Certainly, it may be understood that in some other embodiments, the heating element 222 may not be limited to the heating film. In some other embodiments, the heating element 222 may be a heating sheet. In this embodiment, the heating element 222 may include a bent portion 2221 and a straight portion 2222. The bent portion 2221 may be in two sections, the bent portion 2221 may be located on two opposite sides, and may be connected by the straight portion 2222. The straight portion 2222 may be in three sections, and one end of the straight portion 2222 may be connected to the bent portion 2221. The bent portion 2221 increases internal resistance through bending so that a temperature of the bent portion 2221 is higher than a temperature of the straight portion 2222 in an energized state, and a temperature in a corner area of the bent portion 2221 is a highest temperature.

In this embodiment, the heating component 22 may further include conductive connection portions 223. There may be two conductive connection portions 223. The two conductive connection portions 223 may be respectively connected to two ends of the heating element 222, and may pass through the vaporization core 221 to be electrically connected to an electrode member 24. In this embodiment, the conductive connection portion 223 may be a lead.

As shown in FIG. 5 to FIG. 7 , in this embodiment, the air guide structure 2120 may be arranged on the vaporization base 21. The air guide structure 2120 may be used to guide the airflow in an air flow path, and guide the airflow to the vaporization surface 2214 on the heating component 22. In addition, the vaporized vapor on the vaporization surface 2214 may be directly guided into the air outlet channel 213 through the air guide structure 2120, thereby increasing an amount of vaporized vapor. Specifically, in this embodiment, the air guide structure 2120 may be arranged on an end surface of the inner sleeve 21 facing the vaporization surface 2214, and a set distance D may be left between the air guide structure 2120 and the vaporization surface 2214. That is, the set distance D is left between a bottom surface of the air guide structure 2120 and the vaporization surface 2214. The air guide direction of the air guide structure 2120 may be set to align with the position with a highest temperature on the heating element 222, that is, set to align with the bent portion 2221, so that vapor from an area that generates the largest amount of vapor may be exported, thereby increasing the amount of exported vapor.

Further, in this embodiment, the air guide structure 2120 may include two air guide grooves 2121. The two air guide grooves 2121 may be provided on an end surface on which the inner sleeve 212 is arranged opposite to the vaporization surface 2214, may be distributed on two opposite sides of the vaporization surface 2214, and may be provided in parallel. Specifically, the two air guide grooves 2121 may not be on the same straight line, so that the introduced airflow does not form a confrontation, thereby causing the vapor to disperse. It may be understood that in some other embodiments, the two air guide grooves 2121 may not be limited to being provided in parallel, nor be limited to being not on the same straight line. In some other embodiments, specifically, the two air guide grooves 2121 may be provided opposite to each other and located on a straight line. It may be understood that, in some embodiments, a quantity of air guide grooves 2121 may not be limited to two. In some other embodiments, a quantity of air guide grooves 2121 may be one or more than two.

A set distance D may be left between the air guide groove 2121 and the vaporization surface 2214. In this embodiment, a plane on which the air guide groove 2121 is located may be arranged slightly higher than the vaporization surface 2214, and the set distance D of the air guide groove 2121 may range from 0.5 mm to 1.5 mm. When a height range is greater than 1.5 mm, the introduced airflow cannot touch the vaporization surface 214, and a problem of carbonization of the heating film occurs; and if the height range is less than 0.5 mm, problems of insufficient air inflow and insufficient amount of vapor occur. In this embodiment, the air guide direction of the air guide groove 2121 may be set to align with the position with a highest temperature on the heating element 222, that is, may be set to align with the bent portion 2221.

In this embodiment, the air inlet area of a single air guide groove 2121 may range from 0.6 mm² to 1.5 mm². When the air inlet area is less than 0.6 mm², the air inflow is insufficient; and when the air inlet area is greater than 1.5 mm², vapor dispersion occurs and the amount of vapor decreases. A sum of air inlet areas of the two air guide grooves 2121 may range from 0.8 mm² to 3.0 mm², so that the air inflow may be increased, and then the amount of the vaporized vapor may be increased.

Certainly, it may be understood that in some other embodiments, the base body 231 may not be limited to be in a shape of an ellipse. The base body 231 may be in snap-fit connection to the shell 1. In some embodiments, buckles 2311 may be arranged on two side walls that are arranged opposite to each other of the base body 231, and the base body 231 may be in snap-fit connection to the shell 1 through the buckles 2311. In this embodiment, an air inlet 2312 may be provided on the base 23. Specifically, the air inlet 2312 may be provided on the base body 231, and there may be two air inlets 2312. The two air inlets 2312 may be distributed on a short axis of the base body 231, and are in communication with the air storage cavity 215 respectively. In this embodiment, a first through hole 2313 may further be provided on the base body 231, and there may be two first through holes 2313. The two first through holes 2313 may be provided at intervals, so that two electrode members 24 may be mounted on the two first through holes 2313 in a one-to-one correspondence manner. In this embodiment, two second through holes 2313 may further be provided on the base body 231. The two second through holes 2312 may be located on two opposite sides of the two first through holes 2313, so that magnetic members 25 may be mounted on the two second through holes 2312. The matching portion 232 may be arranged at one end of the base body 231, so that the second sleeve portion 2112 of the vaporization base 21 may be sleeved on the matching portion 232. In some embodiments, a support structure 2312 may further be arranged at one end of the matching portion 232. The support structure 2312 may be inserted into the vaporization base 231, and may be used to support the heating component 22. In this embodiment, the support structure 2312 may include two support arms that are arranged opposite to each other.

The two electrode members 24 may be mounted in the first through hole 2313 in a one-to-one correspondence manner, so that the heating component 22 may be connected to the power supply assembly.

In this embodiment, the vaporization assembly 2 may further include magnetic members 25, and there may be two magnetic members 25. The two magnetic members 25 may be mounted in the two second through holes 2314 in a one-to-one correspondence manner, and may attract and fix the entire vaporizer with the power supply assembly.

FIG. 10 to FIG. 12 show the second embodiment of the electronic vaporization device of the present invention, which is different from the first embodiment in that the two air guide grooves 2121 are provided in parallel and are located on a straight line.

After the airflow is guided to the vaporization surface 214 by the air guide structure 2120, a flow direction of the airflow may be changed by using vaporization cavities of different shapes. Compared with the airflow of the second embodiment, the airflow of the first embodiment is smoother. In the first embodiment and the second embodiment, a structure of an inlet adaptation section and a structure of the air outlet channel 213 are substantially the same, but a design of the vaporization cavity 214 is different. A main difference is that the airflow enters the vaporization cavity 214 from the adaptation section (the second connection portion 2142) at a different velocity horizontal angle, and a shape of the adaptation section (the second connection portion 2142) from the vaporization cavity 214 to the air outlet channel 213 is different, so that uniformity and fluidity of the airflow are different. Specifically, reference may be made to comparative analysis of a pressure field and a velocity field of the first embodiment and the second embodiment.

As shown in FIG. 13 and FIG. 14 , inhalation resistance of the airflow channel in the first embodiment and the second embodiment is mainly caused by two parts: the air inlet channel and the adaptation section (the second connection portion 2142) entering the vaporization cavity 214; and the inhalation resistance of the first embodiment is 713.5 Pa, and the inhalation resistance of the second embodiment is 918.3 Pa. Compared with the inhalation resistance of the first embodiment, the inhalation resistance of the second embodiment increases by 28.7%. A main reason for the small inhalation resistance of the first embodiment is that a cross-sectional area of an inlet channel of the vaporization cavity 214 is relatively large. The local resistance loss of the air entering the vaporization cavity 214 is small, and the airflow channel at the outlet of the vaporization cavity 214 is smoother, generating a small vortex and less resistance loss.

As shown in FIG. 15 and FIG. 16 , compared with the first embodiment, there are two relatively large vortex areas in the vaporization cavity 214 of the second embodiment. A vortex in an area 1 causes an increase in the inhalation resistance of the airflow channel and intensifies condensation of vapor. A vortex in an area 2 causes a vaporization medium to not be taken away in time, and a temperature of the heating element is too high.

As shown in FIG. 17 and FIG. 18 , because the two air guide grooves 2121 of the vaporization cavity 214 of the second embodiment are on the same straight line, after the air enters the vaporization cavity 214 from the two air inlets, a “stagnation area” appears at the heating element in the middle, a large vortex (as shown in a dotted box in the foregoing figure) is generated. Most of the airflow is not fully diffused in the vaporization cavity 214, and directly flows out to the air outlet channel. The air guide grooves 2121 of the first embodiment are staggered with each other, so that the air enters the vaporization cavity 214 and fully diffuses. Velocity distribution in a heating element area is more uniform, and the air may be fully mixed with the vaporized liquid vaporization medium and then flow out of the vaporization cavity 214.

Based on the foregoing analysis, it may be learnt that compared with that in the second embodiment, the airflow in the first embodiment is more uniformly mixed and the flow is smoother.
